Each circle’s x-position maps to GDP, y-position to population, and radius to life expectancy, with all values drawn from the included `bubblechart.csv` file. Hovering highlights a circle with a black stroke. The chart is built using D3 v7, employing `d3.scaleLinear` for axes and radius encoding, rendered as SVG circles, with axis labels generated via `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/94ed4a867482445995e1a9119e44c91c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
